Norton 78072769291 Abrasive Belt 150 Grit 3x21 Aluminum Oxide

Product Description

The NORTON 78072769291 is a coated abrasive belt designed for dry belt sanding operations on stationary and portable belt sanders. Constructed with an aluminum oxide abrasive grain on a heavyweight cloth backing (X-weight), this belt delivers consistent cut and durability across a range of sanding tasks. At 150 grit, it falls in the very fine grade range, making it well-suited for finish sanding and surface preparation before coating or sealing. The closed coat density ensures maximum abrasive coverage for smooth, uniform stock removal. This belt is part of the Norton R228 series.

This belt is intended for dry sanding applications in woodworking, metal fabrication, and general maintenance environments. At 3 inches wide and 21 inches long, it fits standard 3 x 21 inch portable belt sanders commonly used by carpenters, finish carpenters, metalworkers, and maintenance technicians. The very fine 150 grit is appropriate for final material prep, light deburring, and smoothing surfaces prior to finishing. It is not rated for wet sanding use.
